## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-3990df3e -d '<json body>'
```

Example prompt: Check if the PyPI package 'requests' has any active CVEs or GHSA security advisories and tell me what patched version I should upgrade to.

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go modules, or Rust crates — especially when you need CVE and GHSA advisories together with patched version recommendations in a single call, without self-hosting an OSV scanner or managing API keys directly.

## Known failure modes

- Unknown or misspelled package name returns empty results or 404
- Invalid ecosystem prefix causes validation error
- OSV.dev upstream timeout results in 503 or degraded response
- Package with no known vulnerabilities returns empty advisories array
- Missing required 'package' field returns 422 validation error

## How this service works

Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and returns active CVEs, GHSA advisories, and patched versions. (Live x402 v2, IETF MPP & MCP endpoint at https://polymarket-odds.agentdiet.dev/v1/cargo-vuln-scan)

## Output

Returns a list of active vulnerabilities for the queried package, including CVE identifiers, GHSA advisory IDs, severity ratings, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
